EXTREMITY IMAGING APPARATUS FOR CONE BEAM COMPUTED TOMOGRAPHY

摘要

An apparatus for cone beam computed tomography can include a support structure, a scanner assembly coupled to the support structure for controlled movement in at least x, y and z orientations, the scanner assembly can include a DR detector configured to move along at least a portion of a detector path that extends at least partially around a scan volume with a distance D1 that is sufficiently long to allow the scan volume to be positioned within the detector path; a radiation source configured to move along at least a portion of a source path outside the detector path, the source path having a distance D2 greater than the distance D1, the distance D2 being sufficiently long to allow adequate radiation exposure of the scan volume for an image capture by the detector; and a first gap in the detector path.

主权项

1. A method for obtaining tomography images of a portion of a leg, the method comprising:
positioning the portion of the leg to be imaged along a β axis in a scanner that comprises a radiation source and a detector that are disposed to orbit the β axis and atop a first weight sensor; positioning the leg to be imaged within the scanner and a leg that is placed on a second weight sensor that lies outside the scanner; displaying one or more values indicative of the weight distribution between the first and second weight sensors; and energizing the radiation source to direct radiation through the portion of the leg being imaged and toward the detector and obtaining one or more images at different angles.
